PROBLEM 4: Would you drink blue soda?
You know from experience that the smell of food stimulates your appetite. You even say that the
flavor of the food tastes different by just smelling it. Did you know that our vision also interacts with
the taste of the food? Although sight and taste have separate receptor organs, their close
relationship affects how you perceive the flavors of food. Our eyesight triggers our taste buds by
initiating a neural response.
Did you know that Pepsi used to have blue-colored Cola? Also known as Pepsi Pinas, Pepsi Blue was
introduced in the Philippines in 2002. It was PepsiCo's attempt to introduce a non-traditional colored beverage.
Unfortunately, this berry-flavored cola was not a successful product and was discontinued a few years later.
Arci, a food technology student, wishes to investigate whether teenagers prefer a blue-colored soda. She
randomly selected 50 undergraduate students from her university and obtained their consent to participate in a
food tasting experiment. For her experiment, she prepared two glasses of soda for each student: a clear-colored
soda and the same soda flavor mixed with a blue food coloring. The addition of food coloring is not expected to
alter the actual taste of the soda since food coloring is tasteless. The sampled students will first taste the clear-

The addition of food coloring is not expected to alter the actual taste of the soda since food coloring is tasteless. The sampled students will first taste the clear-
colored soda and then the blue-colored soda after an hour. After each taste test, the students will be asked
whether they like the taste of the soda they drank.
Consider di = Xblue - Xdlear where Xblue is the number of students who prefer both the clear-colored and blue-
colored sodas Xclear is the number of students who prefer the clear-colored soda but not the blue-colored soda.
